SUMMARY

One or more aspects of this disclosure describe systems and methods configured to generate virtual entities representing real-world users. The generated virtual entities may be used in virtual environments. The virtual environments may include one or more of a gaming environment, an animation, a video, and/or other virtual environments. By generating virtual entities representing real-world users that may be used within the virtual environments, the systems and methods presented herein may increase a level of immersion the real-world users have when interacting with the virtual environment. An implementation of a system described herein may generate virtual entities representing real-world users using one or more of one or more imaging devices, one or more depth sensors, one or more physical processors, and/or other components. The system setup may provide the users with quick and affordable systems to generate virtual entities representing real-world users; and therefore may increase the viability in using virtual entities representing real-world users in virtual environments.

A system configured to generate virtual entities representing real-world users may include one or more of one or more servers, one or more computing platforms, one or more imaging device, one or more depth sensors, a network, one or more external resources, and/or other components.

The one or more servers may include one or more of one or more physical processors, one or more non-transitory electronic storage, and/or other components. The one or more physical processors may be configured by computer program instructions. Executing the computer program instructions may cause the one or more physical processors to facilitate generating one or more virtual entities representing one or more real-world users. The computer program instructions may include one or more of an image component, a body component, a head component, and/or other components.

In some implementations, non-transitory electronic storage may be configured to store one or more of a base body model, one or more default body models, a skeleton model, a base head model, one or more default head models, and/or other information.

The base body model may be defined by a set of values for a set of body modeling parameters. The set of values for the set of body modeling parameters may specify one or more characteristics of the base body model. The base body model may be a virtual body model of a generic male and/or female body type.

The body component 106 may be configured to determine correspondence values conveying correspondences between the appearance of the user's body and individual ones of the default body models. The body component 106 may generate the body of the virtual entity representing the real-world user based on the determined correspondence values by modifying the set of values defining the base body model based on determined correspondence values and the sets of base values defining the default body models such that the base body model may be modified to model the appearance of the body of the user.

In some implementations, there may be individual correspondence values for the individual default body models. For example, a first default body model may have a first correspondence value and/or a second default body model may have a second correspondence value. The first correspondence value and/or second correspondence value may be determined independently. The first correspondence value may convey correspondences between the appearance of the body of the user and the first default body model. The second correspondence value may convey correspondences between the appearance of the body of the user and the second default body model.

In some implementations, correspondence values may be determined based on one or more of a user body dimension ratio, a base body model dimension ratio, a default body model dimension ratio, and/or other values. The correspondence values may be determined based on relationships between the user body dimension ratio, the base body model dimension ratio, the default body model dimension ratio, and/or other values. In some implementations, the relationships between the user body dimension ratio, the base body model dimension ratio, the default body model dimension ratio, and/or other values may be one or more of a difference, a ratio, a correlation, and/or other relationship between the one or more values. In a non-limiting example, the correspondence values may be determined by comparing the ratio of the difference between the user body dimension ratio to the base body model dimension ratio and the difference between the default body model dimension ratio to the base body model dimension ratio. In a non-limiting example, a correspondence value may be determined by the equation:

${{Correspondance}\mspace{14mu}{Value}} = \frac{\begin{matrix} {{{user}\mspace{14mu}{body}\mspace{14mu}{dimension}\mspace{14mu}{ratio}} -} \\ {{base}\mspace{14mu}{body}\mspace{14mu}{model}\mspace{14mu}{dimension}\mspace{14mu}{ratio}} \end{matrix}}{\begin{matrix} {{{default}\mspace{14mu}{body}\mspace{14mu}{model}\mspace{14mu}{dimension}\mspace{14mu}{ratio}} -} \\ {{base}\mspace{14mu}{body}\mspace{14mu}{model}\mspace{14mu}{dimension}\mspace{14mu}{ratio}} \end{matrix}}$

The relationship between set of values of the surface parameter may be one or more of a difference, a ratio, a correlation, and/or other relationship between one or more the height, the width, the depth, the focal length, and/or other values of the surface parameter.

In a non-limiting example, a user body dimension ratio may be a ratio between a value specifying the depth multiplied by a value specifying the width over a value specifying the focal length over a height. The user body dimension ratio may be summarized by the equation:

In some implementations, the user body dimension ratio may be one or more of a relationship between set of values the torso parameter, the values for the height parameter, and/or other parameters. The relationships between the set of values the torso parameter, the values for the height parameter, and/or other parameters may be one or more of a difference, a ratio, a correlation, and/or other relationship between one or more of the set of values the torso parameter, the values for the height parameter, and/or other parameters. In a non-limiting example, the user body dimension ratio may be a relationship between a first value for the width parameter, a second value for the depth parameter, a third value for the focal length parameter, and a first value for the height parameter. The relationship may be the value of the first value for the torso width parameter multiplied by the second value for the depth parameter over the third value for the focal length parameter over the first value for the height parameter.

In some implementations, the default body model dimension ratio may be one or more of a relationship between the individual set of base values for the set of body modeling parameters.

In some implementations, the base body model may be modified based on the correspondence values and default body models such that the base body model resembles the user's body. The base body model may be morphed based on the individual default body models. The body component 106 may modify the set of values defining the base body model based on determined correspondence values and the sets of base values defining the default body models such that the base body model may be modified to model the appearance of the head of the body.

In some implementations, the correspondence values may specify a weight and/or influence individual default body models have in the modification/morphing of the base body model. By way of non-limiting illustration, the correspondence values may range between zero to one. In a non-limiting example, a first correspondence values for a first default body model may have the value V1. A second correspondence values of a second default body model may have a value V2. The value V1 and the value V2 may range between zero and one. The value V1 may specify the how much the base body model may be modified to look like the first default body model (e.g. the base may look V1 percent like the first default body model). The value V2 may specify the how much the base body model may be modified to look like the second default body model (e.g. the base may look V2 percent like the second default body model). In a non-limiting example, the base body model may be modified to appear 50% like the first default body model and/or 90% like the second default body model. A sum of the modification of the base body model by the default body models may result in a modified base body model that resembles the appearance of the body of the user.

In some implementations, the individual default body models may include a female body model. The gender of the real-word user may be determined based on the image information and/or depth information, wherein the base body model may be modified/morphed based on the determined gender of the real-word user. Based on the determined user gender by machine learning technique and/or other techniques, the base body model may be modified to resemble the female body model.

In some implementations, the head component 108 may be configured to generate a virtual head of a virtual entity representative of the head of the real-world user.

For example, a first default head model may have a first correspondence value and/or a second default head model may have a second correspondence value. The first correspondence value and the second correspondence value may be determined independently. The first correspondence value may convey correspondences between the appearance of the user's head and the first default head model. The second correspondence values convey correspondences between the appearance of the head and the second default head model.

In some implementations, the head component 108 may obtain one or more of the user head information, individual default head model information, base head model information, and/or other information from one or more of the image component 104, the non-transitory electronic storage 122, and/or other components to determine one or more of the correspondence value conveying correspondences between the appearance of the head and/or face of the user and default head models.

In some implementations, the correspondence values may be determined based on the one or more of the feature maps of the user head, individual default head models, base head models, and/or other information. The feature map of the user's head may be referred to as a user feature map. The feature map of the default head models may be referred to as a default head model feature map.

In some implementations, the individual correspondence values may be determined by the proportions of the one or more head shapes and/or facial feature of the individual default head models for modifying the set of values defining the base head model. In a non-limiting example, a first correspondence value determined based on a first default head model with the value 0.1 may represent the first default head model with a smaller nose proportion may be used on modify the base head model. The first correspondence value determined based on the first default head models with the value 0.9 may represent the first default head model with a larger nose proportion may be used on modify the base head model.

In some implementations, the differences between the appearance of the user's head and the default head models may be determined by comparing the user feature map with the default head model feature map. The correspondence values may be determined based on the differences between the feature points of the user feature map and the default head model feature map. The set of feature individual points of the user feature map may be compared with the set of individual feature points of the default head model feature map to determine the differences between the feature points of the facial features.

In some implementations, a sum of the distances between the set of individual points of the user feature map and the set of the default head model feature map may be determined. The correspondence value may be selected to minimize the sum of the distances.

The head component 108 may modify the set of values defining the base head model based on determined correspondence values and the sets of base values defining the default head models such that the base head model may be modified to model the appearance of the head of the user. A sum of the modification of the base head model by the individual default head models may result in a modified base head model that resembles the appearance of the head of the user.

The user's face texture information may be an image of the user's face. The face texture information may be mapped onto the face of the virtual head based on the feature map of the virtual head of the virtual entity and/or the feature map of the user's face texture. The user's face texture information may be obtained from the output signals of the one or more imaging device(s) 119. The user's face texture information used to map onto the face of the virtual head may be selected based on the user's head orientation relative to the one or more imaging device(s) 119. The user's head orientation may be determined by the feature map of the user's head based on the one or more imaging device(s) 119.

In some implementations, user's face texture information individual facial features of the user's face texture information may be mapped onto the virtual head model separately. For example, the user's face texture information corresponding the eyes may be mapped onto the virtual head model separate from the user's face texture information corresponding the face.
